摘要： PROBLEM TO BE SOLVED: To provide a novel process which improves the yield and production of a reaction product by inhibiting the progression of the deterioration of a catalyst due to the heat formed by the reaction in the process for producing the reaction product by supplying a reaction raw material to a plate-type reactor filled with a catalyst to subject the reaction raw material to reaction. SOLUTION: The process for producing a reaction product includes supplying a reaction raw material to a plate-type reactor having an arrangement of a plurality of heat transfer plates having a plurality of flow paths of a heating medium formed by allowing two sheets of corrugated plates in the form of a circular arc, an elliptical arc, a rectangle or a polygon to face each other and joining the projections of both corrugated plates to each other and catalyst layers formed by allowing the projections of the neighboring corrugated plates to face the recesses thereof at predetermined intervals to subject the reaction raw material to reaction. The heating medium is supplied to the plurality of flow paths of the heating medium formed on the heat transfer plates and the flow direction of the heating medium is changed to the direction opposite the previous flow direction each predetermined period of time passed from the initiation of producing the reaction product.

摘要： The present invention provides a method for handling a (meth)acrylic ester-containing solution in which the (meth)acrylic ester-containing solution is treated by at least one process selected from washing, neutralization and extraction, the said method being capable of ensuring a stable continuous operation of the treating system for a long period of time without deteriorating a liquid-liquid separation efficiency and a distillation efficiency in subsequent steps while inhibiting the formation of sludge, when waste water or a waste aqueous solution obtained by recovering effective ingredients from the (meth)acrylic ester-containing solution treated by said at least one process is recycled to the previous process and reused therein. The above waste water or waste aqueous solution is previously cooled to a temperature of 10 to 50°C and then solids are removed therefrom prior to recycling the waste water or waste aqueous solution to the previous process and reusing the same therein.
